This series implements feature of shared object building as described in:
http://wiki.qemu.org/Features/Modules
The main idea behind modules is to isolate dependencies on third party
libraries from qemu executables, such as libglusterfs or librbd, so that the
end users can install core qemu package with fewer dependencies. And only for
those who want to use particular modules, need they install qemu-foo
sub-package, which in turn requires libbar and libbiz packages.
It's implemented in three steps:
1. The first patches fix current build system to correctly handle nested
variables and object specific options:
[01/09] ui/Makefile.objs: delete unnecessary cocoa.o dependency
[02/09] make.rule: fix $(obj) to a real relative path
[03/09] rule.mak: allow per object cflags and libs
2. The Makefile changes adds necessary options and rules to build DSO objects:
[04/09] build-sys: introduce common-obj-m and block-obj-m for DSO
3. The next patch adds code to load modules from installed directory:
[05/09] module: implement module loading function
[06/09] module: add configurable module whitelist
A few more changes are following to complete it:
[07/09] Makefile: install modules with "make install"
[08/09] .gitignore: ignore module related files (dll, so, mo)
In the end of series, the block drivers are converted:
[09/09] block: convert block drivers linked with libs to modules
v8: This version introduces two runtime loading checks:
* Module init function no longer with __attribute__((constructor)), and
mangled with per configure fingerprint. See patch 05.
* Module whitelist as configure option.
[04] Link libqemustub.a to DSO. (iscsi needs qemu_get_vm_name).
Fix single object module link.
Fix extract-libs to also extract .o libs that'd be expanded later from
.mo.
[05] Add init function name mangling.
[06] New.
[07] Fix typo in "make install". [Daniel]
